aria have inventedinew and useful I-m rovernents in Adjustable Tables, of which tefollowing isj alspecificationa.. -1 t I V -Qur invention-relates to tables "and the like and it has for its object "to provide an adjust-' able table designed more especially for the use With the foregoing in mind t e nature of utility and ractical advantages willbe fu understood romthe following description and claim when the'same' are read in connection with the drawings, accompanying and-forming part of this specification, in which: Figure 1 is a side elevation of the coihbined device constituting a practical embodimentof our invention. Fig. 2 is a horizontalsection taken in the lane indicated by thefline' 22 of Fig. 1, looliing downward. Fig. 3 is an enlarged detail vertical section illustrative of the manner in which the uprights of the table are adjustably fixed with respect to each other. Fig. 4' is a detail section taken in the plane indicated by the line 44 of Fig:

platform is adjustably fixed to the arm on which thesame is mounted. Fig. 5 is a detail horizontal section illustrating the means for adjustably fixing-the uprights with respect to each other. Fig. 6 1s auelevationof a portion of the upper upright; the said figure being shown as broken.

Similar letters designate corresponding parts in all of the views of the drawings, re-

A is the base of our novel table, which is though not necessarily, of general T-shape in plan, and may be provided manufacturer.

B is the lower upright of the-table, which junction of the The said uprigh rounded at a two portions of the base. t B is tubular, and is surpoint adj acnt tothe base A by designed to receive kerosene and tartar emetic with a view of effectually preventing ants or similar insects from findmg their way to the upper ortion of the u said upright B Specification of Letter; ]?a'.:t 'eiit. u yitainieiiiiii irhii 2a, 1908. swarm. 422,'7s2.

Telescoped in the lower upright B is the pear.

upper upright F which is also referably tubular forja purpose which wili a vertical groove f, best and 6, and it is also pro-. of said groove at interthereof with sockets g.

'vals in the length plunger E is drawn outward When the against the action of the spring e, the said plunger will and guided in the tion of a set screw be withdrawn from one of, the sockets 9 but will remain in the groove g, and consequently will prevent turning of t e upper upright about its axis incidental to upward or downward movement of said upright. It will also be manifest that when the plunger E is released and permitted to move inward' under the action of spring e, the said plunger will enter the first socket 9 that is presented to it and in that way adj ustably fix theupper section F against upward or down ward movement. In this connection it will be noticed that the collars of the plunger E is designed to so limit the outward movement of the plunger E as to preclude withdrawal ofthe inner end of the plunger from the groove f.

To the upper upright is connected a T- joint G, and to the said T-joint is also connectd a horizontal in cross-section On the said arm H are mounted the lugs. h and i of the platform I, lug i is the inner end por J, the threaded portion of which bears in a threaded aperture in adrpending piece 7' on the under side of the plat form adjacent to one edge thereof. Because of this provision it will be manifest that the platform I may be adjustably fixed in a'hori-- ody hereinafter a The said u per upright is provided in its outer side with shown in'Figs. 3, 5 vided in the bottom ody D through a conventional swinging oint K is a horizonal tubular arm L. This arm L is designed to carr an illuminating medium which may be eit er an incandescent lamp M the filament of which may be su plied with current throu h wires N carried t ough the arm L and t e tubular upri hts, or a gas burner which may be su p 'ed with gas through the u rights and t e arm L, in the discretion of t e manufacturer. We would also have it understood that when neither electric current or gas is available the arm L may be'a'dapted to support a lamp or other illuminating medium.

As before stated our novel table is designed more especially for the use of bed-ridden ersons, and in such use of the table it ,wil be understood that a ortion of the base A will extend below the bed while the will be disposed above the bed. t will also be apparent that our novel-table may be used to advantage by a person seated in a chair and for conveniently holding a book or for any other purpose.

In addition to the practical advantages that We have ascribed to our novel table, it will be readily observed that the table is not unduly expen sive and is strong and hence well adapted to withstand the usage to which devices of corresponding character are ordinarily subjected.

latform I cut, is:

In an adjustable table, the combination of a base, a tubular upright fixed to and rising from the base, a cup-shaped-bod fixed on the said uprightand surrounding the same, a radiall movable plunger guided in the side wall 0 the said body and in the wall of the upright and having a collar for enga ing the inner side. of the side wall of the iody, a spring disposed in and connected to the body and curved about the upright and also connected to the plunger and arranged to move the plunger inward, an up er upright telescopcd in the lower uprigl it and having a vertical groove in its outer side and also having sockets at intervals in the length of the bottom of said groove adapted to receive the inner end of the plun er, and a latform connected to and mova le with t e upper upri 'ht.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
